Iron Ore

Cooler Top gas

Recycle gas compressor

CO2 continuous sequestration H2O device, by absorption

Reactor

CO2 sold to external use Natural Gas make up for process

Reformer O2

Natural Gas heating “Beverage Quality Standard”: < 50 ppm HC DRI < 0,1 ppm H2S < 20 ppm Moist

So CO2 is sold as a “by – product” American Steel Experts’ Dialogue in the framework of the IEA Global Sustainable Technology Roadmap for Iron & Steel 5 Low Carbon Energy cases at Ternium ~ 1.7M tCO2 recovered in past 10 years Puebla and Guerrero integrated facilities - MEXICO
